Blackstar Amplification ST.JAMES 50/EL34 Manual Del Propietário página 7

WARNING: The output marked '1x16 Ohm' should never be used at the same time
as any of the outputs marked '1x8 Ohm or 2x16 Ohm'. Failure to correctly match
the impedance of the amplifier and speakers will damage the amplifier.
NOTE: Unlike many other valve amps, these have clever sensing and switching
which means that they can be used without being connected to a speaker load.
If the speaker lead is disconnected at the amplifier end then it will automatically
switch it to a safe, low power consumption mode.
When using the STBY 0 mode then the output is automatically switched to the
internal reactive load, meaning the speaker connection is disconnected anyway.
Therefore, for example, if you wish to record using the head and take the output
from either the XLR, stereo jack, or USB, then you can set it on your desk without
any need to be connected to a speaker load.
IMPORTANT NOTE: The protection sensing is at the speaker output jacks on
the unit. So, do not disconnect at the speaker end only. Disconnect at the amp!
5. CAB RIG SPEAKER SIMULATED OUTPUT - MONO BALANCED XLR D.I.
OUTPUT socket
This output is for using an industry standard 3 pin XLR cable for connection to
a recording device, stage box or mixing desk. This provides a low noise, low
impedance, quality connection for recording or live use.
The signal will be the actual speaker output signal (including power valves and
output transformer), that has then been passed through the CAB RIG technology,
to apply the authentic feel and response of a 'mic'd up guitar speaker cabinet in a
room'. The actual sound is dependent on the CAB RIG switch setting and the more
in-depth settings within the CAB RIG software.
More on this in the separate CAB RIG documentation.
As it is derived from post-power amp then the Master control will affect the signal
level sent from this socket.
6. CAB RIG SPEAKER SIMULATED OUTPUT - STEREO JACK LINE OUT /
PHONES socket
This ¼" TRS jack socket provides a stereo connection to connect to a recording
device or mixing desk. Always use a good quality TRS (stereo) type lead or TRS
to 2 x TS (mono) (see diagram below).
It can also connect to headphones therefore allowing silent practice with the
STBY switch set to '0'.
Again, the signal will be derived from the actual speaker output via the CAB
RIG technology, providing a high-quality authentic 'mic'd cab' response. The
actual sound is dependent on the CAB RIG switch setting and the more in-depth
settings within the CAB RIG software app.
More on this in the separate CAB RIG documentation.
The signal level from this output will also be controlled by the MASTER control.

When using headphones, please take into consideration that loud sounds over
extended periods can result in hearing damage, both short term, long term and
permanent. We spend a long time making our amps sound good, so we'd prefer
that you have a long life of good hearing to be able to enjoy them.

7. CAB RIG Switch
This allows the user to switch between the three currently stored CAB RIG settings.
Almost unlimited further options and permutations are controlled and set in the Cab
Rig software.
More on this in the separate CAB RIG documentation.
8. Effects Loop Return Socket
Connect the (mono) output of an external effects unit here.
9. Effects Loop Send Socket
Connect the (mono) input of an external effects unit here.
10. Effects Loop Level Switch
The Level switch sets the effects loop to either +4dBu or -10dBV, which enables the
user to use it with either professional audio equipment (+4dBu) or with guitar level
effects such as effects pedals (-10dBV). If unsure, use -10dBV to start with.
11. Footswitch
The supplied 2-way footswitch can be connected here. The footswitch will enable
the selection between Channel I and Channel II and also select between the two
Voice / Boost settings of Channel II.
Note: Using this socket will disable the front panel Channel and Voice / Boost
switches. Therefore, full control via the footswitch is granted irrespective of how the
amplifier is set. When using the supplied footswitch, the Channel and Voice LEDs
on the amplifier will always display the current setting. On the footswitch, if VOICE /
BOOST is selected for CH. II then this LED will remain lit even when on CH. I, to let
the user know the CH. II settings before they go to it. This prevents any surprise of
difference in gain or volume when switching channels.
EXTERNAL SWITCHING: This socket can also be used by people who wish to
control the channel and voice / boost switching using an external switching device
that connects via a common TRS jack to jack connection.
